[email protected] Mauritia flexuosa has one of the widest distributions of all palms, covering millions of hectares across northern South America, where it forms extensive, high-density stands. How does a species reach this wide distribution and high abundance in the face of strong competition in hyperdiverse tropical forests as well as persist through extreme landscape and climate changes throughout the Cenozoic (last ca. 65 mya)? Evolutionary success is related to historical contingency, genetic variation, and demography. Here I present a robust approach to understanding diversification in the tribe Lepidocaryeeae, showing how clade competition contributed to persistence through geological time. Within the Mauritia lineage, I show extinction patterns using the pollen fossil record, leading to low species diversity in the genus. I also review how climatic change during the Quaternary influenced the extant demography and distribution of M. flexuosa. Mauritia flexuosa presents significant genetic differentiation among different river basins and between the Amazonian and Cerrado biomes. Touching on environmental correlations across the genome, I conclude by contrasting adaptive selection with genomic plasticity. Our work provides new insights into the historical factors that affected geographical distribution and structured genetic diversity, contributing to long-term evolutionary success. Key words: biome, demography, genetic diversity, outlier loci, phylogeny. Spikelet pairs in Andropogoneae Elizabeth A. Kellogg1 1Donald Danforth Plant Science Center. [email protected] Presence of paired spikelets is often used to help identify members of Andropogoneae. Developmentally, the paired spikelets originate from an enlarged branch meristem that converts rapidly to spikelet meristems, one sessile and one pedicellate, a pattern controlled by a uniquely derived genetic network. This pattern is shared even by species described as having triplets of spikelets (e.g. Sorghum, Chrysopogon), in which the triplet is actually a pair plus a terminal spikelet that is morphologically identical to the pedicellate one. The pair is also subtended by an abscission zone, the position of which is synapomorphic for Andropogoneae s.s. In other panicoid grasses, the abscission zone forms below the spikelet and the change in position occurred before diversification of the tribe. In Andropogoneae spikelets of the pair have partitioned the ancestral functions, with one being dedicated to seed bearing and largely encased in a hard covering (glume) and the other staminate, sterile or missing entirely. When present, the pedicellate spikelet serves as a nurse tissue providing photosynthate to the developing seed in the sessile spikelet. The diagnostic - and uniquely derived - character for Andropogoneae is thus not just the pair of spikelets, but also the position of the abscission zone, the underlying genetic network, and the functions in dispersal and photosynthesis. The morphology of a simple pair of spikelets thus offers additional layers of insight into evolutionary mechanisms and potential selective forces. Key words: dispersal, genetic network, pedicellate spikelet, photosynthesis, synapomorphy.
